SMF48A Description

Short technical summary and product information.

The Littelfuse SMF48A is a TVS (Transient Voltage Suppressor) diode from the SMF4L series, designed for surface mounting in a SOD-123F package. This component offers protection against voltage transients, making it suitable for general-purpose applications.

 

Key electrical characteristics include a 48V standoff voltage and a 77.4V maximum clamping voltage. It can handle a peak pulse current of 2.6A and a peak pulse power dissipation of 200W at a 10/1000μs waveform. The operating temperature range is from -55°C to 150°C.

 

Designed for surface mounting, the SOD-123F package optimizes board space. The device is rated for 400W peak pulse power dissipation at 10/1000μs and 2000W at 8/20μs. It also provides ESD protection up to 30kV (Air and Contact) per IEC 61000-4-2.

 

This TVS diode is ideal for protecting sensitive electronic equipment from voltage spikes in consumer electronics, power supplies, and portable devices. Its low profile and surface mount capability facilitate integration into compact designs.
